Slack MCP vs Discord MCP
Searches messages, threads, and channel metadata in a Slack workspace, and can post when given a token with write scope. The search half is immediately useful; the posting half deserves a human checkpoint. Start read-only and add the write scope…

versus: The agent supports a community and needs public discussion…
Bottom line
Slack is where work conversations live; Discord is where communities do. The agent follows the people.
The short answer
Both expose channels and messages, and the difference is the social context. A Slack workspace is a company: permissions are organisational, and summarizing a channel can leak something. A Discord server is a community: membership is public, and the interesting content is community support. Choose by which environment the agent is meant to read.

What would change our mind
A project going archived, or a maintainer changing the install path, flips this comparison faster than any feature release. Both entries are re-checked weekly, and the date above tells you how much to trust the details.
